PDF to AVIF, explained
Convert PDF to AVIF directly on your device. Create a still AVIF image with alpha using a lazy local WASM codec. Choose pages and resolution before rendering.
Choose PDF files and confirm the preview and page count.
Choose a page range and resolution, then keep AVIF selected.
Convert and download the AVIF results. Multiple results can be saved together as a ZIP.
Reading your PDF source
Choose All pages or Selected pages with a range such as 1, 3–5. Each selected page is rendered locally, in document order, and filenames keep the original page numbers. A PDF can contain at most 50 pages.
Settings for AVIF output
Choose quality 1–100 or lossless. The shared quality scale does not imply equal quality across codecs. AVIF encoding is slower than native JPEG and downloads a separate codec only when used.
Dimensions in PDF to AVIF
Choose Screen (108 PPI), 150 PPI or 300 PPI and review each selected page’s estimated pixel dimensions. Resolution controls rendered pixels, independently of compression quality. Optional resize in Advanced Settings applies afterward; the preview shows final output dimensions as well. PDF pages are rendered onto white. ICO output then fits that raster into 256 × 256 pixels.
What survives the conversion
Output stores decoded 8-bit pixels. Lossless preserves those pixels, not original HDR, bit depth, metadata or animation. Check gradients and compatibility before sharing. Inspect small text, symbols and fonts. Rendering flattens document structure: text is no longer selectable, links stop working, and no OCR or extraction of original embedded images is performed.
Batch processing and device limits
Each document must fit 64 MB and 50 pages. Selected pages are checked before full rendering against 24 megapixels, 16,384 pixels per side and a 256 MB estimated pixel-buffer budget. Lower resolution if necessary. PDF batches render sequentially; actual browser memory may exceed the estimate. Total outputs must fit 256 MB.
